Abstract

Bei einem gebauten Kolben mit einer Kugelkopf-Kolben-Pleuel-verbindung sollen Werkstoffehler weitgehend vermieden werden.
Hierzu weist der Kolben folgende Merkmale auf:
  • das die Kugelpfanne beinhaltende Abstützungsteil (3) hat eine maximale Längenausdehnung in Axialrichtung des Kolbens von 60 % des Kolbendurchmessers und besteht aus geschmiedetem Stahl,
  • der Kolbenschaft (6) ist als gesondertes, nicht mit dem Abstützungsteil (3) einstückiges Schaftteil ausgebildet,
  • der maximale Durchmesser des Abstützungsteils (3) ist mindestens 5 % kleiner als der Durchmesser des Schaftteils (6).
